两项新的研究表明，缺乏锻炼会增加患卵巢癌和疾病死亡的风险。研究人员发现，生活中没有娱乐体力活动的人比那些经常锻炼的人患卵巢癌的可能性增加了百分之34。

Two new studies suggest lack of exercise is associated with an increased risk of ovarian cancer and of death from the disease.

In one study, the researchers analyzed data from more than 8,300 ovarian cancer patients and more than 12,600 women without ovarian cancer.Those who said they had done no recreational physical activity during their lives were 34 percent more likely to develop ovarian cancer than those who exercised regularly, the researchers found. The link between inactivity and a higher risk of ovarian cancer was seen in both normal-weight women and those who were overweight or obese.The findings were recently published online in the journal Cancer Epidemiology, Biomarkers and Prevention.

Kirsten Moysich is a professor of oncology at Roswell Park Cancer Institute, in Buffalo, N.Y., and the senior author of both studies. She told UPI, "Women may be overwhelmed with mixed messages about physical activity or exercise recommendations and opt to be inactive because they feel that they cannot meet the recommended amount of physical activity."
